Since Google largely tends to favor ranking informational websites over commercial websites, some authoritative blogs tend to rank for valuable queries based on posts they make in passing.

Even if you had no intent to monetize a post, it just became easier to monetize accidental rankings. If you use analytics to track your stats and notice that you start ranking for some good keywords you can use Triggit to embed links to merchant products directly in the text of your blog post.

allow you to keep your pages clean (and easy to link at) until they rank, then have you add monetization after you have a leading market position for related keywords

Triggit ads are easy to set up and should require little maintenance on the end user's side, but they are still a small start up, so if you start doing well with them make sure you remember which pages do well so you can keep monetizing the pages if the Triggit partnership stops working, and so you can track which pages you should try to monetize more aggressively and/or build links to.

As blended semi-editorial in content ad networks like these evolve, the distinction between optimization and spam blurs. And since Google has a similar product, it is going to be hard to view this in a negative light without looking hypocritical in the process. From Google's pay per action page:

Text links are hyperlinked brief text descriptions that take on the characteristics of a publisher's page. Publishers can place them in line with other text to better blend the ad and promote your product.

For example, you might see the following text link embedded in a publisher's recommendatory text: "Widgets are fun! I encourage all my friends to Buy a high-quality widget today." (Mousing over the link will display "Ads by Google" to identify these as pay-per-action ads).

Though the maximum length of a text link is 90 characters, we've found that shorter links perform better because they allow the publisher use the link in more places on her/his site and in different context. The maximum length is 90 characters but less than 5 words is best. Even better, just use your brand name to offer maximum flexibility to the publisher.
